:MATH:OPTion:THReshold2? 
Set or query the threshold level of source B in logic operations. The default unit is V.   
(-4 x VerticalScale - VerticalOffset) to 
(4 x VerticalScale - VerticalOffset) 
  This command is only applicable to A&&B, A||B, and A^B logic operations of which 
source B is an analog channel.   
  VerticalScale refers to the vertical scale of source B 
VeticalOffset refers to the vertical offset of source B 
The step is VerticalScale/50 
The query returns the threshold level in scientific notation. 
:MATH:OPTion:THReshold2 0.5 /*Set the threshold level of source B in logic   
operations to 0.5V*/ 
:MATH:OPTion:THReshold2?            /*The query returns 5.000000e-01*/

:MATH:OPTion:FX:SOURce1 
:MATH:OPTion:FX:SOURce1 <src> 
:MATH:OPTion:FX:SOURce1? 
Set or query source A of the inner layer operation of compound operation. 
{CHANnel1|CHANnel2|CHANnel3|CHANnel4} 
The query returns CHAN1, CHAN2, CHAN3, or CHAN4. 
:MATH:OPTion:FX:SOURce1 CHANnel1 /*Set source A of the inner layer operation of 
compound operation to CH1*/ 
:MATH:OPTion:FX:SOURce1?                        /*The query returns CHAN1*/
